Two articles from the New York Times, one in 1992 heralding the arrival of PC Maps, another in 1994 after the product was renamed "City Streets":

The 1992 article was called "Practical Traveler; The Maps Are In the Computer".  How long ago was 1992?  The article advises potential buyers that the program requires "about 460 kilobytes of free working memory.  A hard disk is required."  Later on, the article goes on to mention, "CD-ROMs, little disks similar to the musical kind, are catching on as a way to package computer programs."  The operating system at that time was MS-DOS.  Microsoft Windows was still a work in progress at the time, and Al Gore had not yet invented the internet.
